When I connect from home (about 30 miles away - with few amount of hops) there is no problem. A contractor in London however (some 200 miles away) has issues with dropping. He says he has no issue with people near to us but I am skeptical. I have set the bandwidth to low, which reduces quality but improves performance somewhat. He says it is our ISP - but do you think there is a subtle but ultimatly more important issue here, such as his firewall? My connection after all is fine.

hi
yes it can be a firewall but it also could be your isp. check the isp if it resets the connection if its cach is full or if there might be a polocy thast they restart your connection. also see if your router isn't perhaps the problem(if you are using a router)

Used a network analysis tool to simulate PCAnywhere from external source through network. No obvious problems. Still kicking the remote admin off.
Disabled firewall. Still kicks the remote admin off.
Spoke to ISP who identified that we had a variable throughput - potentially the cause of the problem, if you think about it. This was fixed according to ISP. Remote admin still being kicked off.
Replaced network topology with new setup. Setup now goes:

MODEM -> PATCH PANEL -> PATCH PANEL -> SWITCH -> HOST (x8)

Still kicks remote admin off.

Modem, Firewall and Router all the same box. Can now replace this - I have an exact copy handy - But first what kind of problem should I be looking out for, bearing in mind there is no variable throughput on our network...everything seems, well, fine to me :)

I'm beginning to think this is due the amount of hops resulting in some dropped packets. It's perfectly feasible.

Manage projects of all sizes how you want. Great for personal to-do lists, project milestones, team priorities and launch plans.
- Combine task lists, docs, spreadsheets, and chat in one
- View and edit from mobile/offline
- Cut down on emails

There appears to be an issue in how PCAnywhere runs it's session. Of course, much of it's information is run on UDP but a decent percentage is also TCP - I guess used for controls (for administering commands) and a logging system which of course has to be exact. It just has so much functionality that it hinders it. Running in a lower screen resolution helps but it just seems to sercome to lag and packet loss. Many programs can run with a high packet loss. This one, it seems, cannot. This is essentially the answer. I now use Webex which runs on port 80 i.e. over http, which i'm very happy with.

The version with the issue was 12.1. As far as I'm aware others haven't experienced any problems in the latest version or versions preceeding this.

Even if you have implemented a Mobile Device Management solution company wide, it is a good idea to make sure you are taking into account all of the major risks to your electronic protected health information (ePHI).

After creating this article (http://www.experts-exchange.com/articles/23699/Setup-Mikrotik-routers-with-OSPF.html), I decided to make a video (no audio) to show you how to configure the routers and run some trace routes and pings between the 7 sites…
